My little flockof fourteen Buff Orpingtons have yet to lay an egg. They are now 20+ weeks old. It also appears that our large beautiful female ( Big Mama ) may also be "Big Papa" since it appears to show dominant behaviour and crows a lot Is it about time for them to start laying or could "Big Papa" be putting them off ? Another thing while i'm at it; the birds seem to prefer to gather together on the floor of the coop. Sometimes a couple will use the brood boxes to sleep in but mostly they huddle up in a corner and ignore the roosts. Another thing as well, they prefer the coop to the run for the most part during the day. Odd behaviour or normal at this developmental stage ? Chris.
